Interesting that most of the review period was spent with either an old 15 watt per channel, low-end Pioneer receiver or a 35 watt per channel, tube integrated amp. Sounds like they work well with modest power. Of course, from what the salesman at the mall said, the Acoustic Wave music system II might be a better choice. Actually, I'm quite happy with just the smaller Wave music system, but I expect to be moving sometime this summer, and maybe I'll find room to properly place some 901's.

In part three of this review Jeff is going to hook up these 901's to his reference tube gear and reference interconnects and speaker cables...this should be a real ear opener !!

Jeff is NOT even using the Bose equalizer in this review and these speakers do sound MUCH better when you use the equalizer too !....

If Jeff does keep these 901's he should remove all these "FiberGlass" grilles because they do sound much more DIRECT this way and way less colored after you cover all those plastic parts sticking way out from those speaker drivers with teflon tape, on the back side of these speaker !

Jeff should do a update review with these tweaks done on them so people can find out about the full potential of these latest 901's !!

"Jeff is NOT even using the Bose equalizer in this review and these speakers do sound MUCH better when you use the equalizer too !...."

Why do you think the reviewer is not using the equalizer? The review includes a picture of it plus some detail on the sonic effect of the various controls. Interestingly, the reviewer says the bass button acts like a loudness button, but the Bose manual specifically states that it is not a bass enhancement switch and is not intended to boost the bass response of the speaker; from the specifications (-6 dB at 35 Hz), it seems to serve more as a bass attenuation switch. The Stereophile review of an older version mentions this same switch, and that it can be useful in alleviating bass resonances that are a function of the room dimensions.

"If you look down this page your find out that Jeff did NOT use the equalizer..."

From the context, that appears to apply only to one of the "variations on a theme" that he'll explore more in part three. HiFiGuy528's question was specific to when the 901's were hooked up to the Pass XA200.5 mono blocks and ARC REF 5SE; even then, some equalization would seem to be required--it will be interesting to read the details when they are available.
